Cement is a very important building material. It is used in almost all the constructions and is subjected to water in contact. If the concrete or cement is water-absorbing then leakage will occur and will destroy construction. The material used for checking this absorption of water is known as water proofing compound. Water-proof cement is used in water-tanks, sever pipes and so many other constructional like dams, bridges etc. Due to its applicability in numerous construction works, the demand for this product is continuously increasing now-a-days. Moreover, due to uneven supply of the product, there is a good demand for it, and a project for its manufacture on small scale can be visible.
